IMPROVEMENT IN MACHINES FOR BEATING OUT AND MOLDING SOLES 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 177,355, dated May 16, 1876; application file November 4, 1s75.

To all whom it may concern.-

Be it known that l, SIMON Ross, of Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Beating Out and Molding Soles, of which the following is a specification:

My invention relates to machines for beating out and molding soles used in the manufacture of boots and shoes; and the invention consists of a novel combination and arrangement of parts, which will be fully hereinafter described and specifically pointed out in the claim, a preliminary description being, therefore, deemed unnecessary.

1n the accompanying drawings, Figure l is a sectional plan view of a machine embodying my invention. Fig. 2 is a transverse sectional elevation of the same; and Fig. 3 a longitudinal elevation, with the regulatingvalve chamber in section, and with part of the bed-plate and driving machinery removed.

On the bed plate A, at one end, is mounted an air-chamber, B, upon which are mounted the air-pump G, regulating-valve chamber D, safety-valve E, cylinder F, piston G, arch-bar H, guide-bars I and Land the molds or formers used in the shaping of the material under pressure; and on the other end of the bedplate A the driving machinery is fixed, consisting of a shaft, J, running in 'journalsK and K, to which are attached the drivingpulley M and crank-plate N. To connect the crank-plate N with the piston O a pitman, P, is used, which is joined to the piston O in such a manner as to compensate for its movement around the crank-plate N. pump 0 consists of a piston, 0, cylinder to, and valves 1) and c, the valve 1) opening inwardly for the admission of air when the piston is moving outwardly and the valve 0 re- During the pistons return the valve 1) is closed and the valve 0 is open, and allows the air to pass through the ejectionpipe 6 into the air-chamber B, which communicates with the valve-chamber D, in which are two connected pistons, f and g, arranged a suitable distance apart, and fitting the chamber D in such a manner as to be air-tight. The piston f remains below the opening it that com- The airmunicates with the valve-chamber D and airchamber B, and is so arranged as to confine the air in the chambers B and D when the piston g cuts off communication between the said chamber and the cylinder F, or until the pressure is sufficient to raise the safety-valveE. When the piston g is located above the openingi, theairis free to pass into the cylinder F ata point below the piston G, raising the said piston, and with it the mold m, upon which is'placed the l material to be pressed, until the molds m and m are brought forcibly together, in which position they will be retained until the piston g is moved by the lever 19 to a'point belowthe opening 1'. The "air is then free to escape through the top of the chamber D, and the piston G, being relieved from pressure, descends easily until its top flange r'rest upon the top of the cylinder F. The arch-bar H is supported and held in position by the guidebars I and I. The flange I", which is part of the piston G, is arranged to fit the guide-bars l and I in such a manner as. to steady the piston Gr while it is moving in the cylinder F.

The machine can be changed from a molding to a beating-out machine by removing the molds m and m and replacing them by the last a and mold a, as shown in Fig. 2. The change canbe readily made, as the molds and lasts are all fitted with a male dovetail slide, and the piston G and arch-bar H with correspondingfemale slides, so arranged as to locate the molds or lasts in the center of the machine.

What I claim as new, and desire to secure by Letters Patent, is-- The combination of an air-chamber, B,valvechamber D, fitted with valves f and g, cylinder and piston F and G, on the cylinder G of which is fixed a mold, m, operating against an upperfixed mold, m, by means of an air p'u'm p, O, substantially as and for the purpose speci-' fied.

In testimony whereof I have hereunto set F my hand this 25th day of October, 1875.

' SIMON ROSS.
